Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700686, here are decompositions:

37 + 8700649 = 8700686
97 + 8700589 = 8700686
139 + 8700547 = 8700686
157 + 8700529 = 8700686
229 + 8700457 = 8700686
433 + 8700253 = 8700686
607 + 8700079 = 8700686
727 + 8699959 = 8700686

Showing the first eight; more decompositions exist.
